Just done this myself on 110 CSW.
Earthed a live after fitting dash console and the heat was immense. Ran through main loom in seconds- needed complete replacement (after just spending a grand getting wiring sorted for MOT equivalent).
Anyway, main loom from Autosparks ran to about 300 quid. Caution: this main loom will require accessory loom plug ins, so know what you have and what you can salvage. My loom needed heated rear window loom and some mini looms off back of switches- these are seldom available now but can be sourced from salvage. I suspect very few vehicles have same wiring configuration due to numerous specs but everything can be added to the basic main loom from AS.
Refit was a bitch and needs full dash removal. Label up cooked loom, all terminals top/bottom before removing and compare with replacement then label up same.
Good luck!
